Insulin resistance is a key driver of Polycystic Ovary Syndrome (PCOS), affecting up to 90% of women with the condition. Early detection using biomarkers can improve diagnosis, prevent complications like type 2 diabetes, and guide personalized treatments.
Here’s what you need to know:
- Hormonal biomarkers like Anti-Müllerian Hormone (AMH) and LH/FSH ratios indicate PCOS severity and its link to insulin resistance.
- Blood sugar and lipid markers such as fasting insulin, triglyceride-to-HDL ratio, and dyslipidemia reflect metabolic imbalances.
- Inflammatory markers like C-Reactive Protein (CRP) and adipokines provide insights into low-grade inflammation and fat cell dysfunction.
- Genetic markers (e.g., DENND1A, INSR) and AI-driven tools are advancing diagnosis precision.
Telehealth platforms, such as Oana Health, are making PCOS care more accessible by offering targeted treatments like topical metformin and personalized plans. These solutions address insulin resistance while reducing costs and improving outcomes.

Main Types of Biomarkers for Insulin Resistance in PCOS
Biomarkers play a critical role in identifying insulin resistance and related imbalances in Polycystic Ovary Syndrome (PCOS). They can be grouped into three main categories, each offering valuable insights into the condition and helping clinicians tailor effective management strategies.
Hormone-Based Biomarkers
Hormonal biomarkers provide essential clues about the severity of PCOS and its connection to insulin resistance. For example, Anti-Müllerian Hormone (AMH) levels often correlate with PCOS severity. Research shows that six months of metformin therapy can reduce AMH levels, which signals improved ovarian function. Additionally, high insulin levels suppress the liver's production of Sex Hormone-Binding Globulin (SHBG), leading to increased free testosterone and worsening hormonal imbalances. Another common finding is an elevated LH/FSH ratio, which indicates disrupted ovarian function often linked to insulin resistance. Studies suggest that metformin is particularly effective in reducing AMH levels in PCOS patients with insulin resistance compared to those without it. These hormonal markers, when combined with metabolic data, provide a well-rounded diagnostic approach.
Blood Sugar and Fat Biomarkers
Markers related to blood sugar and lipids directly reflect the metabolic issues tied to insulin resistance in PCOS. Dyslipidemia - a condition affecting up to 70% of women with PCOS - is a key indicator. Elevated fasting insulin levels can signal insulin resistance, even in individuals with normal glucose tolerance. Abnormal lipid profiles, such as high triglycerides and low HDL cholesterol, are also common in PCOS. The triglyceride-to-HDL cholesterol ratio has been shown to identify insulin resistance as effectively as fasting insulin tests. Research further highlights that women with PCOS have, on average, 27% lower insulin sensitivity than women without the condition, with BMI contributing an additional 15% reduction in sensitivity. These metabolic markers, alongside inflammatory ones, provide a clearer picture of the dysfunction associated with PCOS.
Fat Cell and Inflammation Biomarkers
Chronic low-grade inflammation, a hallmark of PCOS, is captured through fat cell and inflammation biomarkers. One key marker is C-Reactive Protein (CRP), where a moderate increase (usually below 5.0 mg/L) points to low-grade inflammation. Interestingly, elevated CRP levels are more noticeable in women of normal weight, while in obese PCOS patients, these levels are less distinct compared to obese controls. Other inflammatory markers, such as Tumor Necrosis Factor-alpha (TNF-α) and Interleukin-6 (IL-6), are linked to a genetic predisposition for persistent inflammation in PCOS. Additionally, adipokines like leptin and adiponectin, which are hormones produced by fat tissue, provide insights into fat cell function and insulin sensitivity. Their dysregulation contributes to a pro-inflammatory state. Nearly 30% of women with PCOS have significant visceral fat, which further fuels inflammation and metabolic disruption.
How Doctors Use These Biomarkers
Healthcare providers use biomarkers as critical tools to detect insulin resistance in patients with PCOS. However, while these markers offer valuable insights, the diagnostic process is far from straightforward. Understanding their role sheds light on why diagnosing insulin resistance in PCOS often requires a layered approach.
Early Detection and Risk Assessment
Biomarkers play a key role in identifying insulin resistance early, which is essential for preventing complications like type 2 diabetes. With insulin resistance affecting 35%–80% of women with PCOS, early screening can make a significant difference.
Doctors often start with simple physical measurements before moving to blood tests. For instance, wrist circumference stands out as a unique marker, capable of indicating insulin resistance in both lean and obese patients. On the other hand, BMI tends to be more closely associated with insulin resistance in overweight and obese women than in their lean counterparts with PCOS.
Blood-based biomarkers add another layer of precision. Research by Lunger et al. highlights fasting insulin as an efficient screening tool, potentially reducing the need for more burdensome tests like OGTTs. Combining multiple markers can further enhance risk assessments. A study on Brazilian women with PCOS, led by Costa and colleagues, found that the waist-to-height ratio correlated strongly with several cardiovascular risk factors.
Despite these advances, diagnosing insulin resistance remains a challenge due to the complexities of PCOS.
Current Testing Challenges
While biomarkers provide valuable information, their use in clinical settings is not without obstacles. The diverse presentation of PCOS complicates diagnosis, and many surrogate indices lack the sensitivity needed to accurately identify insulin resistance. This can lead to cases being misclassified as insulin sensitive when they are not.
Geographic and ethnic differences add another layer of complexity. Studies show that women from Asia and America are more likely to exhibit the metabolic phenotype of PCOS, while those from Europe and the Middle East often display hyperandrogenic traits. These variations make it harder to apply a one-size-fits-all diagnostic approach.
Another issue is that most biomarkers are studied individually and often lack validation when used in combination. Differences in populations, testing methods, and PCOS characteristics further limit the reproducibility of findings. Additionally, some biomarkers are not specific to PCOS, increasing the risk of misdiagnosis.
In short, the complex nature of PCOS demands a nuanced approach to diagnosis. Combining multiple biomarkers with careful clinical evaluation remains the most effective strategy, even as challenges persist.

New Research on PCOS Biomarkers
Research into biomarkers for polycystic ovary syndrome (PCOS) is advancing quickly, offering new insights into diagnosing insulin resistance. Scientists are moving beyond traditional blood tests, delving into genetic underpinnings and using cutting-edge technology to make diagnoses more precise.
Genetic Markers
Studies with twins suggest that PCOS has about 79% heritability. Genome-wide association studies (GWAS) have pinpointed 30 genomic loci, including genes like INSR, DENND1A, FSHB, and GATA4. Among these, the DENND1A gene stands out due to its role in controlling androgen production in theca cells. Rare variations in this gene are closely tied to PCOS traits.
Epigenetic changes near the DENND1A gene can also increase its activity, leading to elevated testosterone levels. Experiments manipulating its regulatory elements in human adrenal cells have confirmed its link to higher androgen production. Additionally, reduced expression of the Nrf2 gene has been associated with oxidative stress and inflammation in women affected by PCOS.
These findings help explain why insulin resistance can vary significantly, even among individuals with similar lifestyles.
Computer Analysis for Better Testing
Artificial intelligence (AI) and machine learning are transforming the way PCOS biomarkers are identified and analyzed, offering faster and more efficient data processing.
Building on genetic discoveries, researchers are leveraging computational tools to refine biomarker detection. For instance, one study using an SVM model on genetic data achieved a perfect AUC score in identifying molecular clusters linked to PCOS. Similarly, combining metabolomic data with supervised machine learning delivered 100% sensitivity and specificity in detecting PCOS cases.
Machine learning also integrates data from various sources - multi-omics studies, radiology images, lab results, and clinical exams - to better identify PCOS risk factors. Collaborations between Shenzhen Technology University and Shenzhen People's Hospital are focused on designing intelligent algorithms tailored for PCOS detection. These tools aim to help gynecologists overcome challenges in standardizing diagnostic methods, leading to more accurate and efficient assessments.
The range of AI applications in PCOS research continues to grow. These technologies can sift through large datasets to identify genetic and protein patterns, combine lab results with machine learning to improve diagnostic precision, and even predict complications by linking shared diagnostic genes across different risk factors. Over the last decade, PCOS prevalence in China rose by nearly 65%, reaching 7.8% in 2020. Globally, annual cases increased from 1.4 million in 1990 to 2.1 million by 2019.
This progress is paving the way for more personalized and accessible PCOS care, including telehealth options. Advances in biomarker research are playing a crucial role in developing targeted treatments and improving outcomes for those affected.
